If you heard my feature on health care costs, you heard a reference to heart catheterization teams being on call. The line turned out to have extra meaning today, making all those attempts to properly pronounce it in the recording booth worthwhile.At a press conference about emergency care this morning, I learned that Louisville EMS teams now have the ability to transmit EKGs to hospitals where heart catheterization teams will be on call and ready to treat patients based on their EKGs.When I got back to the newsroom, I called Norton Healthcare to find out about their potential split with Anthem Blue Cross/Blue Shield. Both entities were quoted in my health care feature, and now they're at odds over, among other things, reimbursements for care.This could be medical news serendipity or a reinforcement of not only the need for a 24-hour heart catheterization lab, but the necessity of funds, public or private, to pay for it.
